How to Enhance Digital Photos

Digital pictures can become corrupted in number of ways during the acquisition, transmission, compression or encryption. In all cases, enhancement means one thing: fixing. This can be done by image processing algorithms. These fall in two major categories. Those that manipulate pixels directly and those that operate on the Frequency Transform of the image. You will need a software tool called "image editor" to enhance digital photos.
